A Coin Flip or a Coin Holder is basically made up of cardboard which folds and holds the coin firmly.
It protects it from dust, finger oils and other dirt which can contaminate the surface of the coin.
We have 2 types of Coin Flips : Staple Type & Adhesive type.

Regular Coin Flip (Staple Type)

The staple type coin flips or coin holders are most widely used and holds the coins with ease. All you have to do is just place the coin in the center of the flip, fold the flip to half & staple it on four sides. That’s it! We recommend these flips for beginners in coin collection.
